Thanks guys,
Brad, my case is inverse than you; when I bought the truck, it does not coming with the complete emergency system on the wheels, the last owner had the gear box with the driveshaft brake and gave to me as part of the deal.
I like the Scott´s comments, I think if the major problem is to jack up a rear wheel, I would like to take the risk.
anyway guys I like to see other opinions
Thanks, Alfonso
